Hair winding device

ABSTRACT

The invention relates to a hair winding device for taking up and winding on hair strands. A hair winding rod (1), consists of two parts (2, 3) connected with each other in an articulated manner. At least one foil sheet is attached to the rod foaming protective foils (3, 4) which are impermeable to the waving fluid secured to each of the both parts of the hair winding rod to produce a root permanent wave. Those protective foils project by a considerable length transversely to the longitudinal axis of the hair winding rod.

The invention relates to a hair winding device with means of taking upand winding individual hair strands with one hair winding rod,consisting of two parts connected with each other so that they arearticulated, and with at least one foil attached to this.

Such a hair winding device is known from US-A-35 30 863, for example.The foil used here is porous and allows the waving fluid to actuniformly o the hair.

Additionally, two-part hair winding device are also known, e.g. fromUS-A-2046 586 and GB-A 285.

In addition to the normal permanent wave or water wave, there hasrecently been a desire for a so-called root wave, both as a permanentwave and as a water wave. In principle, this is a wave in which onlypart of the hair strands are provided with a permanent wave or waterwave.

For this purpose, clamping of an extremely thin plastic foil togetherwith the hair strand is known from GB-A 2 28 652. When the strands arewound on, part of the hair strands are thus covered by the foil, so thatthis part cannot be waved, as is indeed the intention. In this way, hairstyles are obtained where the hair is waved only from the hair root onthe scalp over a length of 4-8 cm, for example, while the remaining partof the hair remains untreated, depending on the length of the foil.

This method is, however, very time-consuming, inefficient and difficultto handle and also requires a good deal of practice. For this reason,acceptance of this method by customers is initially low.

The extremely thin protective foil, which must be pulled off a roll orwhich is pre-manufactured, tends to stick together as a result ofelectrostatic charging and to fold and is thus overall a veryunmanageable material. This is particularly so because the protectivefoil has to be relatively thin.

The task on which the invention is based is thus to create a hairwinding device of the type specified above which solves this problem forproduction of root permanent waves or root water waves as well as forpartial permanent waves and partial water waves in an amazingly simpleway.

The hair winding device designed in accordance with the invention ischaracterized by the fact that a protective foil which is impermeablefor the waving fluid is attached to each of the two parts of the hairwinding rod for production of a root permanent wave or root water wave,this foil projecting by a considerable length transversely to thelongitudinal extent of the hair winding device.

An arrangement where the two protective foils are secured internally onboth parts of the hair winding rod is preferable.

It is also advantageous if the two protective foils are securedexternally on the hair winding rod on both parts and are secured woundround up to the gap formed by the two parts.

The other claims should be referred to for further embodiments of theinvention.

The invention will now be explained in more detail on the basis of theexample embodiments in conjunction with the enclosed drawings.

The drawings show

FIG. 1 a first example embodiment of a hair winding device in accordancewith the invention;

FIG. 2 a partial view of the hair winding device in FIG. 1 opened up atan acute angle;

FIG. 3 a further partial view of the hair winding device in FIG. 1;

FIGS. 4 to 7 further embodiments of the hair winding device inaccordance with the invention and

FIG. 8 an example embodiment for detachable securing of a protectivefoil.

FIG. 1 shows a hair winding rod 1 consisting of two halves 2 and 3divided in longitudinal direction. The hair winding rod 1 shown here iscylindrical, but may have a slightly smaller diameter towards thecenter, so that a slightly concave curvature is produced in the sideview.

It is also possible to see two protective foils 4 and 5 and a clampingstrip 8 with two openings 9, which can be hooked into a peg 10consisting of two parts 10a, 10b The clamping strip 8 is hooked into apeg 11, which is also divided into two parts 11a, 11b at the other end.In the simplest form, this clamping strip may already represent anarticulated connection between the two parts 2 and 3.

To produce a root permanent wave or root water wave, for example, thehair winding rod, 1 is opened up and the hair strands are insertedbetween the two parts 2 and 3, whereby insertion is particularly easy.The hair winding rod is then closed and the hair strands are wound on.The part of the hair strands covered by the foils 4 and 5 is thenprotected against the effect of the agents producing the permanent waveor water wave, so that this part of the hair strand is not waved. Theclamping strip 8 is then used to secure the hair winding device on thehead.

FIG. 2 shows a view of the hair winding device in accordance with theinvention from left in FIG. 1 such that the two parts 2 and 3 form anacute angle with each other. It is again possible to recognize parts 2and 3, the parts 10a and 10b of the peg 10 and a hinge connection at theother end arranged between the two parts. This hinge connection isdesignated by 14 here and consists of a flexible material.

FIG. 3 then shows a top view the right side of the hair winding devicewith the parts 2 and 3 and the peg parts 11a and 11b which form the peg.It is also possible to see part of the clamping strip 8, which isindicated by the dash-dot line

FIG. 4 shows a partial view of the hair winding device in accordance theinvention, where the foils 4 and 5 are secured inside on the parts 2 and3 of the hair winding rod.

FIG. 5 shows a similar embodiment with the difference that the foils 4and 5 are glued or otherwise secured on the outer surface of parts 2 and3.

These two example embodiments may be provided either with a hinge rightouter end or with a hinge in the longitudinal direction between parts 2and 3.

FIG. 6 shows a simple example of this type in principle. The foils 4, 5,consisting of one folded piece or sheet, are secured respectively on theinner side of parts 2 and 3 and simultaneously form the articulatedconnection or hinge connection 15.

FIG. 7 shows an embodiment of the invention which is particularly simpleto produce where the part 2 with foil 4 is shown as a single-piece part12 and part 3 with foil 5 as a single-piece part 13, which parts may beconnected either in longitudinal direction by a hinge 15 or at one endwith a hinge 14.

Finally, FIG. 8 shows one of the many possibilities of securing aninterchangeable protective foil 4, where the foil is provided with holesand can then be hooked onto corresponding pegs in one of the two parts,whereby the other foil has corresponding holes, so that the protectivefoils are reliably held when the hair winding device is folded together.

Since is not very expedient to keep a supply of a large number ofdifferent lengths of protective foils separately from the hair windingdevices, and since it is even less expedient to keep a supply of a largenumber of hair winding devices with protective foils of differentlengths, the protective foils 4 and 5 are provided with length markings16, which are preferably designed as required tear-off lines 17. In thisway, it is possible to produce the length required in each case,depending on the customer's wishes, by tearing off a part of each foil.

This new hair winding device possesses a series of unforeseeableadvantages compared with the hair winding devices with "free-flying"protective foils used up to now for root permanent waves:

1. The hair strands can be inserted in the hair winding device simplyeither flush or non-flush, even between the protective foils, and canthus be firmly clamped before winding In this way, it is possible tohold hair strands of different lengths. The hair ends projecting in thecase of non-flush clamping can then still be shortened and evened out.

2. The length of the impermeable protective foils can be selectedarbitrarily from case to case.

3. The hair is not wound round the hair winding device directly duringwinding, but is always inserted between the foils. This is extremelydesirable for hygienic reasons. Foil interchangeability also serves thesame purpose.

4. The use of two foils assures that the waving fluid and the vapoursgiven off by it are reliably kept away from the part of the hair whichis not to be waved.

5. From all this, it can be concluded that considerable simplificationcan be achieved with the help of the hair winding device designed inaccordance with the invention and that the treatment time for windingcan be reduced to approximately half or a third of the previouslyrequired time. Consequently, this method possible with the new hairwinding device is much more customer friendly and could therefore helpthis permanent wave method which protects the hair to spread muchfurther, since the otherwise unavoidable multiple chemical stressing ofthe hair ends is dispensed with.
